cPanel is the most widespread Control Panel instrument on the hosting market. It's feature-rich and it has an easy-to-use interface which will give you full control of your websites. It's easy to control files, email addresses and databases, take a look at usage statistics, install script-driven apps, and many others. The software is preferred by many web hosting companies, since it also has a reseller counterpart named WebHost Manager (WHM). This instrument will offer you a web-based graphical interface, via which you'll be able to control a number of server-side settings, generate website hosting packages or new client accounts and adjust their features with only a few clicks. You may also install different modules and applications, adjust DNS records, brand all the cPanel accounts that your clients will get, add and remove features from their Control Panels, etc. cPanel and WHM are compatible with almost all billing applications out there, so this is among the top platforms when you wish to become a reseller.
